2003 T&C, low beam on drivers side only comes on but will not stay on

Hello, has the headlight switch and wiring connected to the switch been inspected? I have seen on vehicles over the years where the headlight switch overheats causing melting of the terminals or plastic hard shell connector. This is a total guess, but in situation where this happens, you will get cases where the bulbs just kind of go off on their own. I'd say check there next.
